9 Claims.

This invention relates to conduits and has particular relation to distributors wherein a single current of fluid is divided into a plurality of smaller currents.

In making distributing heads which transform I a single current into a plurality of currents, great difficulty has been experienced in so dividing the main current that the smaller currents will be of the same pressure and in the case of dust laden air, it is most desirable to have each small current carry the same amount of dust as each other similar small current.

The primary object of the invention is the provision of an improved distributing head.

Another object of the invention is the provision of a distributing head having a vane for directing fluid currents and having the ends of the vanes adjustable sidewise.

A further object of the invention is the provision of a distributing head having a long vane in the center and shorter vanes on each side for controlling the fluid flow, the ends toward the inlet being adjustable sidewise.

A still further object of the invention is the provision of a distributing head having a vane with both ends movable to adjustable positions sidewise and having pairs of outlets arranged with the plane of their axes parallel to the forward edge of the vane.

Other and further. objects will be apparent to those skilled in the art from a reading of the complete specification and claims.

Referring to the drawings wherein I have illustrated an embodiment of the invention,

Fig. 1 is a horizontal cross-sectional View of my invention.

Fig. 2 is a cross-sectional view on the line 22 ofFig. 1.

Fig. 3 is a face View of the current dividing box.

Fig. 4 is a perspective view showing my invention attached to a blower B mounted on a tractor Similar reference characters refer to the same or similar parts throughout the specification and drawings.

The main body 10 of the distributing nozzle has an inlet opening II which leads to a delivery channel 12. The main body Ill is provided with a flange It] for connection to a flange I3 of a conduit leading from a source of fluid current such as a blower (not shown).

At the opposite end of the main body II] are lugs M for connection to the current dividing box l which has lugs l 5 corresponding in shape and size to the lugs l4 already described. In the embodiment illustrated, there are twelve outlet openings 16 in the dividing box. On the delivery side of the current dividing box I 5 are cylindrical openings l5 to receive the tubesll to whichmay be connected the flexible tubing to lead to the dusting nozzle or other delivering outlet element. A set screw 18 may be provided in each opening l5 to hold the tube I! in place. Adjacent the face or flange l5 is the edge of a converging surface leading to the interior of the tubes H. These converging surfaces intersect at lines l5 and l5 as shown in Figs. 1 and 3. These converging surfaces form guides to direct the divided currents into the cylindrical tubes I1 and serve to change the shape from substantially rectangular to substantially circular in cross-section.

Having described the inlet and outlet, I will now describe the interior of the delivery channel and its operation.

The main body or housing comprises two similarly shaped halves Ill and Ill" having lugs Ii) with openings to receive suitable bolts for holding the two halves together. In the embodiment herein illustrated I place a relatively large vane l9, having pointed ends, on the center line of the delivery channel l2. This vane is mounted so that its ends can be adjusted sidewise to control the flow of the fluid. As herein illustrated this is made possible by a pivot or shaft 20 intermediate the ends of the van-e. The pivot 20 is preferably cast in or otherwise secured within the vane [9 to be integral therewith as farv as practical operation is concerned. The pivot 20 is provided with a hole 2| at one end to hold the same with a nail against turning during adjustment. The opposite end is threaded and is provided with a wing nut 22 to hold the vane against the wall of the housing 10 when the vane is in its adjusted position.

The vane I9 is preferably made hollow and is so shaped as to cause an easy flow of fluid along its sides.

In the form illustrated, there are provided smaller vanes on either side of the relatively large vane l 9. These smaller vanes I have designated 23. If desired, felt washers 24 may be provided on the end of the pivot 20 but between the housing wall and the end of the vanes.

The pivots 20, the holes 2| and the wing-nuts 22 of the vanes 23 are similar to those parts described for the vane 9 and the pivots are also preferably secured in the hollow vanes 23 in a similar manner.

It will be noted that the vanes are all preferably between the ends of the delivery channel and consequently the body of fluid delivered to the openings It is an undivided volume.

It has been found that this delivery head is particularly advantageous in use on plant dusters. It had long been believed that with the same volume of fluid, as air, it would be possible to so design the delivery tube that it would operate the same under all conditions. I have, however, determined that with the same volume of air, an increase in the amount of dust will make necessary a further adjustment.

In adjusting vanes, the wing-nuts are loosened and the vanes placed as near as possible to the direction of fluid flow and all wing-nuts tightened. Then each one is loosened, one at a time, and by a nail in the opening 2!, the vane is adjusted until th proper result is obtained. By this trial method, the vanes may all be brought to the proper adjustment to produce uniform delivery at all tubes H. For a given volume of air and dust, for example only one adjustment should be necessary.

It is to be noted that the current of fluid is taken from an inlet having substantially the same cross-sectional dimensions and this current is changed in shape to a uniform current of substantially rectangular cross-section with one dimension substantially greater than another. Since by the adjustment of the vanes, the same pressure is delivered at all openings l5, it follows that the same amount of dust and air will be deliveredby all tubes ii. The adjustment of the vanes permits of overcoming inequalities in pressure within the tubes ll so that long tubes i! may have the same delivery as short ones.

While I have shown and described, in detail, an embodiment of my invention it is to be understood that modifications and changes may be made without departing from the spirit of the invention nor from its scope as claimed.

Having described my invention what I claim is:

1. A distributing head comprising a body portion having an inlet opening, and a plurality of outlet openings, a plurality of adjustable vanes between and spaced from the inlet and the outlet openings and means for adjustably pivoting one of the vanes intermediate its ends and relative to another vane.

2. A distributing head comprising a body portion having an inlet opening and a plurality of outlet openings, a plurality of adjustable vanes between and spaced from the inlet and outlet openings and means for adjustably pivoting the vanes intermediate the ends of the respective vanes and independent of each other.

3. A distributing head comprising a body portion having an inlet opening, the cross-section of which is of substantially equal width and height and a delivery channel with an end crosssection having one of its dimensions much greater than the other, a plurality of adjustable vanes between and spaced from the inlet opening and the end of the delivery channel and means for adjustably pivoting the vanes intermediate the ends of the respective vanes and independent of each other.

4. A distributing head comprising a body portion having an inlet opening and a plurality of outlet openings, a plurality of vanes between and spaced from the inlet and outlet openings and means for adjustably pivoting the vanes intermediate the ends of the respective vanes and independently of an adjacent vane.

5. A distributing head comprising a body portion having an inlet opening and a plurality of outlet openings, a plurality of vanes between and spaced from the inlet and outlet openings and means for adjustably securing the ends of the respective vanes in various positions sidewise relative to the axis of the head and independently of an adjacent vane.

6. A distributing head comprising a body portion having an inlet opening and a delivery channel, a plurality of independently adjustable vanes in the delivery channel, means for pivoting the respective vanes to move their forward and rearward portions to different points of adjustment relative to an adjacent vane to control the amount of fluid received and its direction of delivery, the vanes being tapered toward their ends and outlet openings adjacent the end of the delivery channel to deliver a plurality of streams of fluid smaller than the inlet opening.

7. A distributing head comprising a body portion having an inlet opening and a delivery channel, a plurality of vanes in the delivery channel, means for independently and adjustably pivoting the respective vanes to move their forward and rearward portions to different points of adjustment to control the amount of fluid received and its direction of delivery, the vanes being tapered toward their ends and outlet openings adjacent the end of the delivery channel to deliver a plurality of streams of fluid each smaller than the inlet opening, the outlet openings being arranged in pairs, the centers of each pair lying in a plane parallel with the axis of one of the pivot vanes.
